    Abstract: A class of quaternary nitrogen-containing polymeric materials, which upon contact with alkali provide substantial light-absorbing or opacifying properties, is disclosed. The polymeric materials comprise repeating units of the formula: ##STR1## wherein the cyclic quaternary nitrogen-containing moiety is a 2-, 3-, or 4-pyridinium moiety; R.sup.1 and R.sup.2 are independently hydrogen, alkyl, substituted alkyl, cycloalkyl, aryl, aralkyl, alkaryl, halo, or R.sup.1 and R.sup.2 together comprise the atoms necessary to complete a six-membered, substituted or unsubstituted benzenoid ring; R.sup.3 is hydrogen or alkyl; X is an anion; and Y is hydrogen, alkyl, substituted alkyl, cycloalkyl, aryl, aralkyl, alkaryl or halo.
